diffusion
Something that can be dissolved in another material is a solute, and is said to be soluble in that material.
They don't so much disappear as become converted to a different isotope - as they throw off particles. If you took the remaining material and added the mass of the particles released as radiation, you should still get the same mass as the original material before the radioactive decay.
Indistinguishable particles are particles that are so similar or identical that they can not be distinguished from another. Electrons and sometimes atoms and molecules can be indistinguishable particles.

Erosion is the transfer of material from one place to another place. Deposition is the settling of sediments to a resting place.
Scattered
Thermal energy in a material causes the particles to vibrate. Particles cannot stop moving altogether, since they would then violate the Heisenberg uncertainty principle. This states that we cannot know a particles speed and position to infinite precision at the same time. A particle in a material that is not jiggling would violate this. The more and faster that the particles are jiggling, the more energy they must have. If they come into contact with particles that are jiggling less, then that energy spreads. The faster jiggling particles slow down, transferring their energy to the slower particles, which speed up. This is just the transfer of heat from one material to another! Here's a good video from famous physicist Richard Feynman explaining "jiggling atoms."

Stephen F. Austin was given another contract to finish settling Texas.

Erosion is the moving of sediment from one place to another place. Deposition is the settling of particles suspended in air, ice, or water due to gravity or friction.
